Abstract: A hand held probe unit has an infrared sensitive thermopile mounted in a metal housing kept at a constant reference temperature by a regulator circuit. A waveguide tube, surrounded by a thermally insulative probe, directs infrared emissions to the thermopile. The thermopile and regulator circuit of the probe unit are electrically connected to processing circuitry in a chopper unit. Prior to taking a patient's temperature, the probe unit is mated with the chopper unit so that the thermopile detects infrared emissions from a reference target which is also kept at a constant reference temperature by another regulator circuit. The processing circuitry repeatedly acquires the output level of the thermopile and stores calibration data. The probe unit is then removed from the chopper unit, the probe is covered with an IR transparent, disposable speculum, and is inserted in the patient's external ear canal. The processing circuitry then determines the patient's core temperature by comparing the stored calibration data to the maximum output of the thermopile during a succession of ear canal samplings.

Abstract: A control system for an angiographic injector precisely regulates the speed of a motor (M) used to expel contrast medium from a syringe, for instance. The control system is centered around a microprocessor (1) which receives commands from the operator via a key-board and then regulates the speed of the motor (M) by supplying drive command pulses to a circuit which integrates the difference in frequency between the command pulses and another pulse train whose frequency is proportional to actual motor speed. The control system also includes a velocity loop which uses the back EMF of the motor (M) to supply an analog voltage also proportional to motor speed to a difference amplifier (20) in a conventional velocity loop. The system is a dual loop controller where the second loop (F) provides approximate .speed control, while the first loop (E) provides a "velocity correction" voltage required to bring the system to zero steady-state speed error. Motor speed pulses are provided by an incremental encoder (9,10), the pulses from which are counted by the microprocessor (1) to limit the volume of fluid injected. Various safety systems guard the injector's performance and help prevent over-volume injections. These systems are part of the velocity control and are also disclosed.

Abstract: An information processing systems having a memory for storing instructions and operands, a central processor unit which includes a mechanism (122) for fetching and decoding instructions and operands and a bus (116, 118, 202) connected between the processor unit and memory. An associated floating point unit (128) is connected from the bus and responsive to decoded floating point instructions for performing floating point operations. The floating point unit and the central processing unit may perform operations independently of the other. There is an improved method and apparatus for executing floating point operations wherein there is a means (226) for determining whether a floating point instruction is a member of a first group of instructions requiring interlock of operation between the central processor unit and the floating point unit or is a member of a second group of instructions not requiring interlock of operation between the central processor unit and the floating point unit. The central processor unit (210, 226) is responsive to the occurrence of an instruction of the first group and to an idle state in the floating point means for dispatching an instruction of the first group to the floating point unit for execution and is responsive to the occurrence of an instruction of the second group and an available state in the floating point unit for dispatching an instruction of the second group. The floating point unit asserts an available signal when the floating point unit is free to accept a next   instruction and asserts an idle signal when the floating point unit is free to accept a next instruction and is not presently executing an instruction or will not be executing an instruction in the next cycle. The central processing unit (210, 226) detects when a floating point instruction of the first group requires a data transfer and asserts a data transfer signal and an end of cycle signal indicating that the bus is available. The floating point unit is responsive to the end of cycle signal and the data transfer signal for synchronizing the floating point clock to the central processor clock and executing the data transfer required by the instruction.

Abstract: TTL circuits are described for generating from an input signal complementary output signals useful in integrated circuit applications. For an enable gate, an alternate enable transistor element is coupled in emitter follower configuration in the enable gate with the base of the alternate enable transistor coupled to follow the enable gate input signal E and provide through the emitter circuit an alternate enable signal A complementary to the enable signal E. The complementary enable signals are applied in an improved TTL tristate output device wih reduced output capacitance. The alternate enable signal A is coupled to the base of an active discharge transistor element at the base of the pull-down transistor of the tristate output device for actively discharging and diverting Miller feedback current caused by transistions on the common bus output when the enable signal E is at low potential and the device is in the high impedance third state. In another application an internal buffer circuit generates complementary data signals by coupling a complementary data signal transistor element in emitter follower configuration in the buffer circuit. The base of the complementary data signal transistor is coupled to follow the input data signal D and provide through the emitter circuit a complementary output data signal D in phase with the input data signal D and complementary to the output data signal D at the output of the buffer circuit.

Abstract: The brush can be used generally both dry and wet and with the brush head in an inclined position. When removed, despite spraying operation, it does not allow washing or cleaning liquid to drip and primarily allows either a soft wiping treatment of the surface using long bristles or additionally using bristle tips of harder action. A preferred embodiment has the following features: A peripheral set (4) of bristle rings which widens towards the bottom in the manner of a funnel, has comparatively long bristles and is composed of two adjacent bristle rings (5, 6). The outer shorter ring (6) serves as a holder for the inner ring (5). When the brush (1) is pressed on, the inner bristle ring (5) spreads out so that some of its bristles rest on the surface (13) (soft treatment). In this case, the stiffer bristles of the ring (6) emerge between the bristles of the ring (5) and hold the bristle wall together for optimum suction conditions; when pressed on further, the bristle tips (9) of the ring (6) reach the surface (hard treatment). A central set (3) of bristles can likewise be brought with its bristle tips (8) to the surface (13). A peripheral spray pipeline (11) and a central spray tube (10) provide the brush (1) with washing or cleaning liquid, the soiled solution of which is sucked off through the central set (3) of bristles and an annular space (12) formed between said set (3) and the peripheral set (4) of bristle rings via the suction nozzle (2). <IMAGE>
